3.2 syllbus
~Organic compounds contain carbon and usually hydrogen.
~Inorganic compounds do not contain carbon and hydrogen.
~ Glucose
Fatty Acid
~-the basic unit of carbohydrates 
-the simplest form of sugar 
-Glucose, Galactose, Fructose 
have the chemical formula C12H22O11, consist of two monosaccharides which are joined by the process of dehydration synthesis (during while a molecule of water is formed)  -Maltose, Lactose, Sucrose 

~ polysaccharides
polymers of carbohydrates, three or more monosaccharides joined together through the process of dehydration synthesis.  -Cellulose, Glycogen, Starch

Glucose-chemical fuel for cell respiration
Lactose- makes up some of the slutes in milk
Glycogen- stores glucose in liver and muscles.

Fructose- found in may fruits, makest them sweet
Sucrose- often transported from leaves of plants to other locations in plants by vascular tissue Cellulose- one of the primary components of plant cell wall

1.A condensation reaction joins two molecules together to form a larger molecule and a water molecule is formed as a result. 2.All biological molecules are formed by condensation reactions. 3. Condensation reactions are also known as dehydration synthesis 4. Condensation reactions can join many amino acids together to form large chains called polypeptides (proteins). 5.Condensation reactions can join many monosaccharides together to form large molecules called polysaccharides (starch). 6.Condensation reactions can join glycerol molecules to fatty acids to form triglycerides.

* Hydrolysis is the reverse of dehydration synthesis. Here a molecule of water is added to break the bonds between the subunits and break the larger molecules down into their smaller components. * Water molecules are used up in hydrolysis.

* When you add water to a polypeptide it breaks down into dipeptides or amino...
